Carrier Aggregation (CA) is one of the promising features to support the much wider bandwidth for packet transmissions in Long Term Evolution-Advanced (LTE-A) systems. To the best of our knowledge, works regarding the packet scheduling algorithm in LTE-A systems with the CA mechanism have not thoroughly been investigated yet till now. In this paper, we(More)
The small-cell base station (SBS) has emerged as a promising technology to improve the network coverage of a macro-cell base station (MBS) for green communications. With the plug-and-play property and without the auto-configuration ability, SBSs are installed unplannedly and unequally. Under such an occasion, it is important to reduce the energy consumption(More)
Carrier Aggregation (CA) is one of the promising features in Long Term Evolution-Advanced (LTE-A) systems. Till now, works regarding the packet scheduling scheme with CA in different frequency bands have not completely been studied and evaluated yet. Thus, the purpose of this work aims to explore such issue and presents an efficient quantized water-filling(More)
Due to the fact that existing 3.5G network cards usually select networks with the highest data rate as their priority choices, the radio resources may not be efficiently and equally utilized in a multiple network environment, even when the network with the highest rate is already congested. In this paper, we propose two dynamic resource allocation(More)
